It will work, but limit you to a pure-cisco environment.  Which, for
many, is enough reason not to touch EIGRP with a 10-foot-pole.

We're happy users of EIGRP since many years - and it has quite some
advantages (debugging why certain paths are selected seems to be much
easier to me in EIGRP than in OSPF/ISIS, and you can do some TE tricks
that a link-state protocol just can't do).

OTOH if I had to re-do our network from scratch, I might go with ISIS,
to get integrated IPv4/IPv6.  Just have one routing protocol to maintain.
(But maybe not - so if IPv4 routing breaks, IPv6 routing might still work)
